91126 is the monicker of a semiconductor integrated circuit developed to meet the need for low-cost, high-efficiency audio amplifiers. The IC has become quite popular with audio enthusiast over the years and finds its way into a variety of applications in consumer, professional and automotive audio.

The 91126 IC was developed using monolithic integrated circuit technology for the purpose of providing good sound quality with low distortion. It offers a wide range of applications including the production of amplifiers, mixer circuits, audio switchers, tone control circuits and even microphone pre-amplifiers.

In the audio amp area, the 91126 offers increased power and voltage capability when compared to other integrated circuits. This makes it suitable for use in more demanding audio applications, and it can usually be used with minimal modification of the circuit. As well as sounding better, an increase in power allows for higher SPL (Sound Pressure Level), and increased bass and treble from the amplifier.

The 91126 has excellent features that make it appealing to audio enthusiasts. Its lower distortion characteristics mean it will produce a clean and clear sound. The IC also features low noise, high output power, wide bandwidth, wide supply voltage range, low quiescent current consumption, low cost and wide operating temperature range.

The operating principle of the IC is based on a technique well known to audio engineers: the use of differential amplifier stages. The IC contains two differential amplifier stages connected in a way that allows them to operate simultaneously and provide the control signals needed for amplifier gain. The IC also contains an output stage and a low pass filter, which helps to reduce any remaining distortion.

The 91126 IC features an on-chip current limiting circuit, which is designed to protect the IC from damage if the output stage is overloaded or short-circuited. There is also an on chip heat sink to prevent thermal runaway problems. The protection circuit helps to ensure that the IC operates safely and reliably.

The 91126 IC is used primarily in consumer and professional audio applications. It is often found in home theater systems, car audio systems, professional PA systems, and even in some high-end audio amplifiers. It is also used in the manufacture of PA systems for commercial and military applications, as well as in some gaming consoles.

For those who are looking for a low cost, high efficiency, and reliable audio amplifier solution, the 91126 IC is an ideal choice. With its low distortion, good sound quality, and wide range of applications, the 91126 IC is an excellent choice for both professional and consumer audio applications.
